Improving Human‐Machine Cooperative Classification Via Cognitive Theories of Similarity

Acquiring perceptual expertise is slow and effortful. However, untrained novices can accurately make difficult classification decisions (e.g., skin‐lesion diagnosis) by reformulating the task as similarity judgment. Given a query image and a set of reference images, individuals are asked to select the best matching reference. When references are suitably chosen, the procedure yields an implicit classification of the query image. To optimize reference selection, we develop and evaluate a predictive model of similarity‐based choice. The model builds on existing psychological literature and accommodates stochastic, dynamic shifts of attention among visual feature dimensions. We perform a series of human experiments with two stimulus types (rectangles, faces) and nine classification tasks to validate the model and to demonstrate the model's potential to boost performance. Our system achieves high accuracy for participants who are naive as to the classification task, even when the classification task switches from trial to trial.     

Teaching about sexuality and veiling in Islam

This article proposes strategies for teaching about sexuality in Islam through student‐centered learning activities, such as self‐reflection, multimedia presentations, and small group discussions. We focus on a diversity of perspectives related to veiling in Islam. The approaches we describe help students deconstruct and reevaluate common U.S. cultural assumptions that equate veiling in Islam with the oppression of Muslim women. Through the use of Likert scale questionnaires and written reflection papers, we have found that students are able to acknowledge and distinguish a multiplicity of perspectives regarding veiling and sexuality in Islam after they have been introduced to academic scholarship on the history of veiling, and after they have had multiple opportunities to engage in small and large group discussions on the topic.     

Is there more to complicated grief than depression and posttraumatic stress disorder? A test of incremental validity

There is growing interest in complicated grief reactions as a possible new diagnostic category for inclusion in the Diagnostic and Statistical Manual of Mental Disorders. However, no research has yet shown that complicated grief has incremental validity (i.e., predicts unique variance in functioning). The authors addressed this issue in 2 studies by comparing grief, depression, and posttraumatic stress disorder (PTSD) symptoms with different measures of functioning (interviewer ratings, friend ratings, self-report, and autonomic arousal). The 1st study (N = 73) used longitudinal data collected at 4 and 18 months postloss, and the 2nd study (N = 447) used cross-sectional data collected 2.5-3.5 years postloss. With depression and PTSD controlled, grief emerged as a unique predictor of functioning, both cross-sectionally and prospectively. The findings provide convergent support for the incremental validity of complicated grief as an independent marker of bereavement-related psychopathology.     

Interdependence,social motives,and outcome satisfaction in multiparty negotiation

What makes negotiators satisfied with their outcomes? In this study, we examined whether interpersonal interdependence, in the context of multi‐party multi‐issue negotiation, affected negotiators' satisfaction with their individual and group outcomes. We integrated principles from interdependence, social comparison, and social value theories to generate hypotheses about the social‐evaluative nature of satisfaction with negotiation outcomes. Controlling for differences in quality of individual outcomes, we found a positive association between satisfaction and individual outcome and a negative association between satisfaction and group outcome. Relative to those with prosocial social value orientation, negotiators with an individualistic social value orientation were less satisfied with the group outcome, regardless of induced motivational orientation. Neither motivational orientation nor an interaction between motivational orientation and social value orientation were related to satisfaction. We discuss the implications of our results for research on interdependence processes in negotiations and the role of social motives. Copyright © 2000 John Wiley & Sons, Ltd.     

Presentation Matters: The Effect of Wrapping Neatness on Gift Attitudes

While gift‐givers typically wrap gifts prior to presenting them, little is known about the effect of how the gift is wrapped on recipients’ expectations and attitudes toward the gift inside. We propose that when recipients open a gift from a friend, they like it less when the giver has wrapped it neatly as opposed to sloppily and we draw on expectation disconfirmation theory to explain the effect. Specifically, recipients set higher (lower) expectations for neatly (sloppily)‐wrapped gifts, making it harder (easier) for the gifts to meet these expectations, resulting in contrast effects that lead to less (more) positive attitudes toward the gifts once unwrapped. However, when the gift‐giver is an acquaintance, there is ambiguity in the relationship status and wrapping neatness serves as a cue about the relationship rather than the gift itself. This leads to assimilation effects where the recipient likes the gift more when neatly wrapped. We assess these effects across three studies and find that they hold for desirable, neutral, and undesirable gifts, as well as with both hypothetical and real gifts.     

Comparing Cognitive Behavior Therapy,Problem Solving Therapy,and Treatment as Usual in a High Risk Population

Cognitive behavior therapy (CBT), problem‐solving therapy (PST), or treatment as usual (TAU) were compared in the management of suicide attempters. Participants completed the Beck Hopelessness Scale, Beck Scale for Suicidal Ideation, Social Problem‐Solving Inventory, and Client Satisfaction Questionnaire at pre‐ and posttreatment. Both CBT and PST indicated significant improvements over time within the majority of measured variables; when compared to TAU, both groups showed significant differences on satisfaction. When PST was compared to TAU, results indicated significant differences on suicidal ideation, indicating overall efficacy of brief therapies with suicide attempters.
